2400W/4-channel Flexible Amplifier with DSP and Dane™

Description

Powersoft Amplifiers Quattrocanali 2404 DSP+D

Overview

Quattrocanali 2404 DSP+D offers the traditionally amazing sound quality and reliability of all Powersoft products.

The patented SRM (Smart Rails Management) technology allows for the maximization of the efficiency of the system and drastically reduces power consumption in any load and usage condition. Quattrocanali features the lowest thermal dissipation in the industry, reducing the need for external cooling devices.

Quattrocanali is designed to operate with Lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two.

DSP+D versions of the Quattrocanali grant in-depth control and monitoring via Armonìa, tailoring the sound and managing the system can be done in a remote, decentralized location.

This Amplifier Platform can also be trusted in mission-critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS.

Features

Power supply

  • Patented output filter with ripple cancellation network
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
  • Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket

Protections

Fully protected circuit design with:

  • Ac protection: shut down the power supply when AC mains voltage is outside the operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against nonaudible, strong, nonmusical high-frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long-term limiter: protects the loudspeaker against steady long-term RMS (nonaudio) signals, by reducing the maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature-controlled continuous variable speed fan, front-to-back airflow
  • Temperature forecast with LCD traced historical behavior

General

  • Fixed frequency switch-mode output stage for high-grade sound accuracy
  • Compact size – all models only 1 RU for reduced rack cost and space
  • Lightweight – for easier racking and shipping: 7 kg (15.4 lbs)
  • Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIO
  • Remotely switchable double input (main and aux) per channel

Settings

  • Built-in defeatable clip limiters for each channel
  • Digital gain-attenuator control
  • Defeatable gate selection for each channel
  • User-selectable gain/sensitivity
  • User-selectable maximum output power for each channel
  • User-selectable maximum mains current draw
  • Lockable set-up by user-selectable access key code
  • Built-in remote control via the RS-485 interface provides full diagnostic, operational setting, and system monitoring

Digital Signal Processing

  • TI C6000 DSP platform
  • AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture
  • Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
  • Delay up to 100 ms for time alignment
  • Active DampingControl™ for cable compensation
  • Peak, RMS voltage, RMS current, TruePower™ limiters

Remote Control and Monitoring

Via Software:

  • Control and diagnostics monitoring via ArmoniaPlus
  • Dedicated WebApp

Via Hardware:

  • Attenuation (from 0dB to 26dB)
  • High-pass filters (35Hz, 70Hz)
  • Lo-Z/Hi-Z/70V/100V output selection
  • Adjustable gain (from 26dB to 35 dB)
